North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer. This is the first day of summer in the Northern Hemisphere and the first day of winter in the Southern Hemisphere.

Roll up your sleeves with us during @SERestoration's #MakeADifferenceWeek! We're hosting a tree care event at David Dunlap Observatory Park on June 2 from 9 to 11 a.m. and need passionate volunteers. Who's in?! Register at RichmondHill.ca/TreePlanting.
